What do you get when you take an already tough Mercedes-Benz G63 AMG 6x6 and toughen it up some more? You get this, the Brabus B63S-700 6x6, which is terrorizing visitors of the Frankfurt Motor Show this month.
The stock model's 5.5-liter Biturbo V8 engine has been tuned to increase its output from 544hp to 700hp, and its torque from 760Nm to 960Nm. This enables this heavy-looking monster of a vehicle to reach 100kph from rest in just 7.4sec. Top speed, however, has been limited to a relatively pedestrian 160kph due to the equally monstrous off-road tires. The engine is mated to an AMG Speedshift Plus 7G-Tronic automatic transmission.
Brabus explains the modification done on the engine: "The production turbochargers are replaced by two special Brabus turbochargers with a larger compressor unit, which produce a higher boost pressure. Brabus Gold Heat Reflection sheathing for the intake and charge-air pipes further lower the charge-air temperature. Specially calibrated Brabus mapping for the engine management system coordinates the perfect interaction of all high-performance components while also ensuring compliance with the stringent Euro V emission standards."
In addition, Brabus says, "special high-performance metal catalysts with 75mm downpipes are installed to lower the back pressure. The stainless-steel sport exhaust system with controlled butterfly valve was custom-developed for the G63 AMG 6x6 and offers both optimized power yield and active control of the exhaust note. Drivers can select at the push of a button between the subtle Coming Home mode and a markedly potent exhaust note in the Sport position. The Brabus exhaust system also puts its visual stamp on both sides of the vehicles with two striking dual sidepipes."
Let's just say this is one vehicle we wouldn't mind parting floodwaters with during rescue missions.
